Forgive my lack of knowledge , however only change I see is are cars starting from 43 to 40 . I think this is great because now "Start & Park " cars can now stay off track !
We've gone back to 36 teams being guaranteed starting spots. You can have 46 cars show up and, while not likely, a 10th place car be sent home because a 43rd place car is guaranteed a starting spot for life.
It's basically franchising. The main thing is to protect the big teams. If Roush Racing goes under, they now have some protection in that, if a new team wants to join the sport, they'd have to buy Roush's charter. It supposedly also makes it easier for a new team to join, buy a charter and not have to worry about making the field, but I just don't see it happening that way.
The days of Alan Kulwicki winning a championship as an owner-driver, or David Ragan winning Talladega with a low budget team, or John Andretti making the field for the Daytona 500 with a start-up team owned by Bob Jenkins, or a Michael Waltrip Racing entering the sport are over.
